drawing

Definition

All needed for drawing something.

Remarks

A xtd::drawing::graphics class is create from xtd::forms::control::create_graphics or xtd::forms::screen::create_graphics or xtd::drawing::image::create_graphics.

And also when xtd::forms::control::paint event is sent, the xtd::forms::paint_event_args contains a xtd::drawing::graphics associate to the control event paint.

Function Documentation

create_graphics() [1/3]

graphics xtd::drawing::image::create_graphics ( )

inline

#include <xtd.drawing/include/xtd/drawing/image.h>

Creates the xtd::drawing::graphics for the image.

Returns

A xtd::drawing::graphics for the image.

create_graphics() [2/3]

static drawing::graphics xtd::forms::screen::create_graphics ( )

static

#include <xtd.forms/include/xtd/forms/screen.h>

Creates the xtd::drawing::graphics for the screen.

Returns

create_graphics() [3/3]

drawing::graphics xtd::forms::control::create_graphics

(

)

const

#include <xtd.forms/include/xtd/forms/control.h>

Creates the xtd::drawing::graphics for the control.

Returns

A xtd::drawing::graphics for the control.

Remarks

The graphics object that you retrieve through the create_graphics method should not normally be retained after the current Windows message has been processed, because anything painted with that object will be erased with the next WM_PAINT message. Therefore you cannot cache the graphics object for reuse, except to use non-visual methods like xtd::drawing::graphics::measure_string. Instead, you must call create_graphics every time that you want to use the graphics object.
